. AUTOMOBILE-HOOD HINGE.

Application filed may 9,

To all whom) it may concern:

Be it known that I, EDWARD L. ACKER- MAN, ing at Detroit, county of WVayne, State of Michigan, have invented a certain new and useful Improvement in Automobile-Hood Hinges, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form-a part of this specification.

This invention relates to hinges for automobile hoods and the object of the invention is to provide a concealed hinge for the automobile hood members whereby the said members have a symmetrical outer surface which is both pleasing in appearance and easily cleaned. A further object of the invention is to provide a concealed hood hinge in which the two hood members are each hinged separately to a supporting member, the edges of the hood members being normally 1n contiguous relation with a central rib or raised portion of the supporting-member when the hood is closed. A still further object of the invention is to provide a concealed hood hinge in which one of the hood members may be swung upwardly and supported in position without contacting other portions of the hood or said central portion. A novel feature of the invention is involved in the construction whereby the usual unsightly hood hinge is eliminated and also in the construction whereby either hood memberis prevented from coming in contact with other'portions of the hood thus preventing marking and disfiguring of the enamel thereon. These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in I the accompanying drawings in which Fig. 1 is a plan view of a portion of an automobile hood partly broken away to show the hinge construction embodying my invention.

Fig. 2 is a section taken on line 22 of Fi 1.

Fig. 3 is a section similar to Fig. 2 showin an alternative form of construction.

Fig. 4 is a section taken on line 4-4 of Fig. 8.

a citizen of the United States, resida 1921.v Serial No. 468,081.

As shown more particularly in Fig. 2 the 4 dev ce cons1sts of a supporting member 1 which is provided with a channel 2 on each side thereof and is also provided with a central rib or raised portion 3 having a flat outer surface adapted to form part of the hood surface when the'hood is closed. The supporting member 1 is provided with side flanges 4 which extend upwardly and are each provided with an inturned' flange 5. Each flange 5 1s provided with knuckles 6 shown more particularly in Fig. 1 which extend about and support a hinge'pintle 7 shown in Figs. 1 and 2. The hood is provided with a pair of sheet metal hood members 8 which are each provided with a return bent portion 9 the said portions 9 being formed at the inner edge with extendlng portions 10, shown more particularly in F g. l, which also extend about the hinge pintles 7. By this construction the hood members 8 are each provided with an edge 11 which when the hood is closed are brought to contiguous relation with the edges of the rib portion 3, as shown in Figs. 1 and 2. By this construction the hood members 8 may be swung upwardly on the hinge pintles 7 and when so turned the members 8 take the position shown in dotted lines in Fig. 2. The supporting member 1 is so formed that upon turning the member 8 to the upper position the edge 11 thereof contacts the inner face of the portion 4 before the outer face of the member 8 strikes the edge of the portion 3 of the supporting member. Thus the members 8 are prevented from contacting any other portion of the hood which prevents marring of the enamel thereon the liability of denting the surface of the hood member.

In Fig. 3 I have illustrated an alternative form of the device. In this case the channel 2 is formed with an upwardly extending wall 12. In this case a separate hinge is provided consisting of a leaf 13, pintle 14 and a leaf 15 which is provided with a depending portion 16 as shown, which is riveted or welded to the wall 12 of the supporting member. To secure the hood member 8 to the hinge the hood member is provided with a return bent portion 17 which extends about the leaf 13 of the hinge and maybe welded or secured thereto in any suitable manner. As shown in Fig. 4 the leaf 13 is provided with knuckles 18 exion tending about the pintle it and the leaf 15 is provided with knuckles 19 also extending about the pintle 14;. The operation of this construction is the same as before described, the hood member 8 being swung upwardly on the pintlesltas a center of rotation until the edge 20 of the hood memher 8 engages the inner face of the wall 12 at which time the member 8, as shown more particularly in dotted lines in Fig. 3, is supported in position without contacting the edge of the rib portion 3 of the supporting member 1. By this construction a hood of very neat appearance is provided in which the usual protruding hood hinge is eliminated, the hinges for the hood members being concealed beneath the hood.

From the foregoing description it becomes evident that the device is exceedingly simple d efiicient in operation, of comparatively low manufacturing cost, providmg a hinge construction very neat outer appearance having severai advantages over the normal construction and provides a device which accomplishes the objects. desired.

Having thus fully described my invention, its utility and mode of operation, what I claim and desire to secure by Letters Patent of the United States is- 1. In an automobile hood, a supporting member having a central rib portion and a substantially U shaped channel portion on each side thereof, each channel portion'having an inwardly turned flange on the outer side thereof, a pintle carried by each flange,

antenna a hood member pivotally mounted on each pintle, the edge of either of the hood members when swung to the upper position engaging a side of the channel portion in a manner to prevent contact with the other portions of the hood.

2. in an automobile hood, the combina tion with the two hood parts, of a central supporting member, a hinge for each hood part having one leaf thereof attached to the respective side or" the central member, the edge of the respective side of the central member, the edge of the respective hood part being bent over and secured to the other leaf of its hinge positioning the axis of no ow distance from the edge of the hood and channei. being of a depth to permit the edges of the hood members to be turned downward thereinto engage a wall of the channel preventing contact with. the other portions of the hood,

in testimony whereof, sign this specific cation.
